Contacts
UT0W
Size 20 contacts for UT0W connectors
Description
Size 20 contacts with a .040” (1.0 mm) pin
diameter are two piece crimp snap-in
contacts in pin and socket version available in:
• Solid machined version
• Stamped and formed version
• Solid machined dip solder contacts :
- 50A7
- 5016
And designed for heavy duty top perfor-
mance requirements.
These contacts consist of a crimp/solder
body made of high conductive copper alloy,
and a stainless steel retaining spring
featuring retention in the housing cavity and
a closed entry socket to prevent probe
damage.
Crimp contacts accommodate AWG20
through AWG26 wire and the crimp
barrels.
All contacts have to be ordered separately.
Features and benefits
• Made from high conductive copper alloy
with gold plate finish.
• Two piece construction with dual purpose
spring which serves for contact retention
and protects the body against damage.
• Stamped and formed contacts packaging:
- On reel: 3000 pcs
- In bulk packing: 100 pcs in plastic bag.
• Solid machined crimp and dip solder
contacts packaging : 50 pcs in plastic box.
